Capacitive deionization has appeared a few years ago as a technology focused to desalination, which, by applying a small potential difference between electrodes promotes the removal of ionic content from the effluent. This condition make itself attractive as a purification or desalination method. Main focus research of this technology is toward to the electrode materials, looking for large surface areas. This is the case of activated carbon, known for its ability to retain ions and molecules thanks to its large surface area. So, in this work the electro-sorption capacity of 3 different samples of activated carbon from four substrates has been evaluated: date, medlar, olive and apricot stones. Specific capacitance was obtained through cyclic voltammetry experiments, using a range of 1 V, exploring the current associated with the induced adsorption and therefore the capacitance per gram that the materials were available to offer.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
